I am a longtime BMW owner and MOA member. I have had many R bikes but never a GS. I am planning a trip to Alaska. Please help with any of the following or more: 1) What bike should I buy if I am going to ride from the Midwest to Fairbanks and on to the Artic Circle? I realize I can make it to Fairbanks on about any bike but not to the Artic Circle. Is a GS the best option? I want to buy the bike, ride to Alaska, return, and sell the bike. Is a used GS1100 the smart option? What about a R1200C since it is so light and easy to handle? I have had a R1200C and thought that might work. If I settle in on trying to buy a GS, is there anything I need to look for other than the usual (one owner, low mileage, acessories, dealer serviced, etc.)? 2) Do GS models have tubeless tires? Are tubeless tires a must? 3) What month should I go? July? 4)What about camping? Obviously, camping is a good option, but what type of places should I look for to be the safest? 4) Route? I have been in the lower part of Alberta and BC so that part is not much of a concern as to the route, so should I just go up the Alaska Highway and back or should I take a different route back? I will be entering and returning the US from Montana or maybe North Dakota. 5) Any other miscellaneous advice would be great.
